Language to Rewards for Robotic Skill Synthesis
Free while signed in. Answers cite the passages they came from.
Google's Language-to-Rewards uses LLMs to define reward parameters for robotic RL.
LLM-defined rewards: Uses LLMs to translate natural-language task descriptions into optimizable reward parameters for downstream RL training.
Real-robot evaluation: Evaluated on a real robot arm, not just in simulation, validating that the approach survives sim-to-real challenges.
Emergent skills: Complex manipulation skills including non-prehensile pushing emerge from the LLM-specified rewards alone.
Natural robot programming: Positions natural language as a practical interface for programming robot behaviors without handcrafting reward functions.
